催化柴油加工路线选择

Selection of Processing Route for FCC Diesel

随着环保要求的提高,国家对成品油质量的要求也越来越高,生产清洁柴油已成为炼油行业的重要任务和责任。在各类柴油馏分中,催化裂化柴油由于硫含量高,密度大,芳烃含量高和十六烷值低,已成为柴油质量升级的主要瓶颈。据预测,"十三五"期间,国内消费市场柴汽比将大幅下降,如何降低柴汽比已成为目前炼化企业面临的主要问题之一。本文结合目前国家对成品油的质量要求和市场对柴油的需求情况,重点分析了催化柴油新型加工工艺的特点及其适应性。认为催化柴油加氢制汽油或芳烃技术可实现催化柴油质量升级的同时,降低柴汽比,在未来将有广阔的应用前景。

With the improvement of environmental requirements, country upgrade fuel quality standard. Producing clean diesel has become an important task and responsibility for the refining industry. In all kinds of diesel fractions, FCC diesel with high sulfur content, high quality density, high content of aromatics and low cetane number, has gradually become the main bottleneck of diesel quality upgrading. According to the forecast, the ratio of diesel oil to gasoline in the domestic market will fell sharply during the 'thirteenth five-year plan', then how to reduce the ratio has become one of the main problems facing the refinery. Combined with the fuel quality and demand, this paper analyzed the characteristics of FCC diesel processing technology and adaptability. The technology of using FCC diesel to produce gasoline or aromatic can improve the quality of FCC diesel and reduce the ratio of diesel oil to gasoline. The technology will have broad application prospects in the future.
